SOLVING INEQUALITIES Lesson 2-9 & 2-10

Math Vocabulary Review Inequality: A math sentence that compares (, ) a point/points on a number line

Review of Graphing Inequalities a) Graph the given point of the inequality b) PointsSymbol(s) (closed)> OR < ◦ (open)> OR < c) Determine what side of symbol the variable is on… “small” pointOR“big” open d) Choose a number to match the symbol side of variable e) Graph solutions (arrow) in that direction m > -4

Solving Inequalities+/- Similar to solving equations: Opposite Integer Math 3 < r + 6 - 6 - 6 -3 < r Graph: ___________________________________________

Solving Inequalities+/- y – 14 < -26 + 14 +14 y < -12 Graph: ___________________________________________

Practice Solve & Graph each inequality: a) 8 + t < 15___________________ b) v – 4 < 7___________________ c) t – 5 > 11____________________

Solving Inequalities x / ÷ 3y < -18 y < -6 Graph:_____________________________________ b > 3 4 b > 12 Graph:______________________________________

Solving Inequalities x / ÷ (w/ negatives) When “doing math” with negatives -3y < -18 y > 6 Graph:______________________________________ b > 3 -4 b < -12 Graph:_______________________________________

Practice Solve & Graph each inequality: a) 4x < 40 b) 36 > -9t c) m > 2 4 d) 5 < r -3
